abstract = {The associated production of a Higgs boson and a top-quark pair is measured
in events characterised by the presence of one or two electrons or muons. The Higgs boson
decay into a b-quark pair is used. The analysed data, corresponding to an integrated
luminosity of 139 fb−1, were collected in proton-proton collisions at the Large Hadron
Collider between 2015 and 2018 at a centre-of-mass energy of p
s = 13TeV. The measured
signal strength, defined as the ratio of the measured signal yield to that predicted by the
Standard Model, is 0.35+0.36
−0.34. This result is compatible with the Standard Model prediction
and corresponds to an observed (expected) significance of 1.0 (2.7) standard deviations.
The signal strength is also measured differentially in bins of the Higgs boson transverse
momentum in the simplified template cross-section framework, including a bin for specially
selected boosted Higgs bosons with transverse momentum above 300 GeV.},
